The RK series power line filters use single-stage filtering to achieve the high differential mode performance required in industrial machinery in noisy environments. A leakage current of 0.16 mA at 120 Vac/60 Hz also suits the filters for portable equipment.

The power line filters are offered in current ratings of 10, 15, and 20 A, and are rated for voltages up to 250 Vac. Targeted applications include high-noise industrial environments, portable equipment, HVAC equipment, switched mode power supplies, vending equipment including ATMs, vending, and kiosks.
